Baruda is basically formulated to be mixed with water at <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />1:30 ratio. This ratio can be adjusted according to the type of surface and use. If you are mixing it with cement, mix about 4-5% of the weight of cement. You must remember that more Baruda improves waterproofing performance, but reduces compression strength. Therefore, always observe the given mixing ratio when applying it on floors that support heavy materials or other areas that require strong compressive strength.
